安装cloud-init

安装cloud-init

ARM_Ubuntu镜像

1、打开terminal，更新包列表；移除`cloud-init` 软件包

sudo apt-get update
sudo apt-get remove cloud-init

如图所示1.1：

2、删除cloud-init相关文件

sudo rm -rf /var/lib/cloud/*;sudo rm -f /var/log/cloud-init*
sudo rm -rf /etc/cloud/cloud.cfg.d/*

如图所示1.2：

3、安装Cloud-Init

sudo apt-get install cloud-init

如图所示1.3：

4、创建目录

sudo install -d -m 755 /etc/cloud/cloud.cfg.d

如图所示1.4:

5、配置 OpenStack 环境的元数据源

sudo tee /etc/cloud/cloud.cfg.d/99-openstack-datasource.cfg >/dev/null <<'EOF'
datasource_list: [ OpenStack ]
datasource:
  OpenStack:
    metadata_urls: ['http://169.254.169.254']
    max_wait: 120
    timeout: 5
    apply_network_config: false
EOF

如图所示1.5：

6、 删除`cloud-init.disabled`文件

sudo rm /etc/cloud/cloud-init.disabled

如图所示1.6：

7、 设置cloud-init相关服务为开机自启动

sudo systemctl enable cloud-init-local.service cloud-init.service cloud-config.service cloud-final.service

如图所示1.7：

8、重启云主机，重新进入桌面

如图所示1.8：

9、查看cloud-init 状态，必须为active才可用

sudo systemctl status cloud-init-local.service cloud-init.service cloud-config.service cloud-final.service

如图所示1.9：

备注：以上为ARM-Ubuntu安装cloud-init步骤，执行完成关机，制作镜像后可进行分享操作

ARM_Euler镜像

  1. 清除所有yum缓存的数据后重新安装cloud-init软件包 
    sudo yum clean all
sudo yum makecache
sudo yum install cloud-init
sudo mv /etc/cloud/cloud.cfg /etc/cloud/cloud.cfg.bak
sudo install -d -m 755 /etc/cloud/

如图所示2.1：

2、配置 OpenStack 环境的元数据源

命令如下（全部内容进行复制）：

sudo tee /etc/cloud/cloud.cfg >/dev/null <<'EOF'

# and system configuration.

# will get a message to login instead as the default $user
